With Tha Carter IV pushed back until August 29, Weezy makes up for it with an apology: Sorry 4 The Wait. The 12 track project sees him going to his mixtape roots, tackling all sorts of instrumentals from "Tupac Back" to "Gucci Gucci." With features from Gudda Gudda, Lil B, Raw Dizzy and more, Tune may be sorry but we can't blame him. We should be thankful.
